Living_Oracles(i)
33 Again, you have heard that it was said to the ancients, "You shall not forswear yourself, but shall perform your oaths to the Lord."
34 But I say to you, swear not at all; neither by heaven, for it is God's throne;
35 nor by the earth, for it is his footstool; neither shall you swear by Jerusalem, for it is the city of the great King;
36 not by your head, because you can not make one hair white or black.
37 But let your yes, be Yes; your no, No; for whatever exceeds these, proceeds from evil.
